Big increase in military flights

There’s an E2 Hawkeye tracking in the north sea. It doesn’t show where it’s taken off from. I’ve never seen one over here before. Makes me wonder if there’s an aircraft carrier in the north sea.

Anyone know where they are flying from?

I answered my own question, seems there is a aircraft carrier in the north sea

There was a C-2 Greyhound that came up from Spain to Prestwick over the weekend. Presumably to bring something needed by the carrier air wing.
